TO ALL WHOM ITMAY CONCERN:

Be it known that I, EBENEZER S. PURDY, of Groton, in the count-ybf lVestchester, and State of New York, haveinvented a newan'tl=useful Mill for Grinding Grapes, Apples, and other Substances; and I do hereby declare thatthe following is afull, clear, and enact description thereof, which will enable -those skilled in the art to make and use the' same,1eference being had to the accompanying drawings, forming part of this specification, in which y Figure 1 is a planorf-topfview of my invention, with the hopper removed.

Figure 2, a side'lse nal view'oflv the same, taken in the line :c x, fig. 3.

-Similar letters of reference indicate corresponding parts, Y

'.lhis'inventon relates to a new and useful improvement in that-class of mills for grinding grapes, apples, vvand otherA substances, in which rotary toothed cylinders are employed, and one cylinder made to rotate witha greater speed than the other. l The invention consists in the alternate airange'ment of the cutting teethoboth cylinders so that the 'teeth will passclosely between each other, but .without` i'mpeding each other, this fl'hely grating-and reducing the fruit or other substance without crushing the same. i l if A represents a-frame, which .may be constructed in any proper manner to support the working parts, and B B 'are two cylinders,'placed on said frame, and connected bygears C C', one. of which, 0,011 the shaft ,of cylinder B, is considerablylarger in diameter than the other, on the shaftof cylinder B, and the latter, cylindelgrB, thlereforefrotates faster'than4 cylinder B, the relative speed in this instance being four `to one. The cylinder B" has four. horizontal rows of teeth, a, upon it, standing at equal distances apa-rt, and arranged` upon alternateconcentric lines, and theother'cylinder, B, is provided with sixteen horizontal rows' of teeth, a', also arranged upon -alternate concentric lines, the relative proportion of the number of rows of teeth on the respective cylindersvcorre'sponding-to the relative speed of" the respective cylinders. This combined horizontal and concentric alternate arrangement of the teeth upon the respective cylinders permits the several rows upon each cylinder to vpass very closely hetweenthe teeth of the opposite cylinder without impediment; whichraction causes the grapes, apples, or other substances which come in contact with the teeth, to bc very thoroughly pulped or grated, but not crushed, as in many other mills.l The hopper D- is placed over the cylinders i'n the usual way for the reception of thefruit or other substances that are to be-acted upon by the mill.

By the alternatelarrangernent ofy the teeth a av on the cylinders B B', each set of teeth on one cylinder passing closely between those-on the other cylinder, the apples or other substances to be ground will undergo a grating process, wl1ereby,no lumps will be formed, and thereby more of thejuice of the fruit will be obtained.

I do not claim broadly'the application of teeth to the cylinders of cider-mills; nor do Ivclaim the construction and application of breakers to the cylinders when armed with teeth, as shown in Letters Patent No. 13,839, granted to W". O. Hickek, dated November 25, 1855, and reissued March 26, 1861; but what I do claim as my invention', and desire to secure by Letters Patent is i The alternate arrangementot the teeth a a on the cylinders B B', the teeth of one cylinder passing closely between the.v teetlrot' theother cylinder, and adapt-ed for grating the fruit instead of crushing'it; the whole being constructed, arranged, and operated in the manner and for the purpose set forth.
